feat: introduce data sink to collect snapshot from each metric periodically

Open empiredan opened this issue 3 years ago • 0 comments

This PR is for https://github.com/apache/incubator-pegasus/issues/1116.

This PR introduces data sink to collect snapshot from each metric periodically. The base data sink is actually an abstract class that has interfaces needed by concrete monitoring systems. The unit test has implemented a data sink and verified if the snapshots can be received correctly.
